Huawei has released the E5372s-32 MiFi WiFi router, which comes in Indonesia locked to the Bolt carrier. It comes with customized firmware and does not accept the unlock code / NCK. The only solution is that flash the device with un-customized firmware, and then only you can unlock E5372.

DC-Unlocker has created software, calls it Huawei E5372 Bolt Unlocker v4, which can be used to unlock customized E5372s-32 Bolt MiFi WiFi router. But, he charges 7 EURO for unlocking one device. I have already tried with all available firmware of Huawei E5372 but no success in flashing the device.

Finally, I got the E5372_Update_21.270.11.00.1151 (Bolt E5372s-32 Downgrader), which flashed the device successfully, and in the firmware upgrade process only, it got unlocked too.

In any case, the firmware update gets failed, then use Huawei R215 – E5372 flasher tool to repair bricked E5372.

6. Wait till finish the firmware update.
